Question:Erratic screen behavior when charging

When I charge my iPhone4 at night, the screen becomes nearly impossible to use. It will select things no where near where I am touching and makes swiping impossible. Doing some tests I concluded it was the charging cube. When not plugged into that cube all works perfectly. I received it from Amazon when I purchased a long charging cable. It has a green dot, whatever that means. Anyone else having this issue or know why this happens? (iMac 27" i7, 8GB) ~ (MacBook, 4GB) ~ (iPhone 4, 32GB) ~ Mac OS X (10.6.5)

Answer:Erratic screen behavior when charging

Erratic screen behavior when plugged in uncommon but not unheard of. Try restoring your device in Itunes as new (backup your data first). After restoring as new, try to plug your Ipod in again. If the issue persists call apple tech support or make an appointment at a retail store. iOS 4

Answer:Erratic screen behavior when charging

Its likely being caused by the cable you purchased from Amazon, which is clearly not an Apple cable. The simplest recommendation is to NOT use the cable. Instead use the charging cable supplied by Apple with your phone. If you still have issues with your screen using the Apple cable, try a full restore, but Im betting not using the Amazon cable will solve the problem. Asus Laptop iPhone 4 and Very Happy With It!

As stated in my post, I did a lot of experimenting and found that only the power cube caused the problem. I had already figured the problem device, I am curious why it causes this problem? (iMac 27" i7, 8GB) ~ (MacBook, 4GB) ~ Mac OS X (10.6.5)

Well for what its worth, when I used the official Apple power cube it works perfectly. I am guessing either the voltage or current regulation is incorrect or there is a incorrect connection within the cube. I will close this out so anyone else with the same issue may more quickly reduce the problem.Cheers (iMac 27" i7, 8GB) ~ (MacBook, 4GB) ~ (iPhone 4, 32GB) ~ (iPhone 4, 32GB) ~ Mac OS X (10.6.5)

But will it cause any further damage to the ipod touch/iphone if we continue to use that charger that causes the erratic screen behaviour?
